' Application filed May 16,

T all 'whomz't may concern:

Be it known that 1," inennr Honn, a citizen of the United States,residing at the city of St. Louis, in the State of Missouri, haveinvented certain new and useful Improvements in Apparatus for Repairingand Testing Radiators, of which the following is a specification. I

My invention has relation to improvements in testing machines forradiators, particularly automobile radiators, and consists in the noveldetails of construction more fully set forth in the specification andpointed out in the claims.

The object of the present invention is to provide a device that willreadily immerse the radiator in a suitable liquid without manualhandling of the radiator. A further object is to provide a testingmachine of the character referred to that may be operated by one person;one that is simple; and one possessing further and other advantagesbetter apparent from the follow-- ing description in connection with theaccompanying drawings in Which- Figure 1 is a top plan of my improvedtesting machine; Fig. 2 is a side elevation thereof; Fig. 3 is a sideelevation of one supporting arm, with the hanger and part of theplatform supported thereby; Fig. 4. is a cross-section through one sideof the table showing an edge view of the platform supporting arm and thepinion for oscillating the same; Fig. 5 is an enlarged view of thenotched sector and pawl for holding the platform in place; Fig. 6 is aside view of the adjustable bearing block.

Referring to the drawings, 1 represents an angle iron frame provided atone end with a drain and working table 2. The frame is supported on thelegs 3, and has a tank 1 positioned Within the angles and suitablysecured thereto. Adjustable bearing blocks 5 are secured to base plates6, by means of bolts 7, said bolts traversing slots 8 in the blocks 5and being screw-seated in the base plates 6, the latter being suitablysecured to the frame 1. The engaging surfaces of blocks and plates areprovided with teeth 9 to prevent accidental displacement the blocks 5after the same have been adjusted. Shafts 10 are mounted in the blocks5, and have sprockets 11 fixed on their outer ends and toothed disks 12keyed near their inner ends Within the tank a. The shafts 10 terminateat their inner ends in studs 13 Specification of Letters Patent.

on which are mounted supporting arms 1 1. The arms 1 1 terminate intoothed disks 15 which engage the disks 12 and are held in engagementtherewith by nuts 16 passed over the studs 13. Hanger arms 17 aresupported on pins 18 projecting from supporting arms 1 1, the upper endsof arms 17 terminating in hooks 19 which are hooked over the pins, andbars 20 are secured to the lower ends of the arms 17, said barssupporting a perforated platform 21.

A shaft 22 is mounted in brackets 23 fixed to the frame 1 below the tank4, said shaft extending entirely across the frame, and sprockets 2 1 arekeyed on the ends of the shaft 22, one of said sprockets having a seriesof operating handles 25 fixed to it. A sector 26 is keyed on one end ofthe shaft 22, said sector having a plurality of notches 27 on itsperiphery, and a dog 28 is mounted on the frame 1 adjacent the sector 26so that when desired said dog may be dropped into any one of the notches27 in order to lock the operating mechanism against movement.

On each side of the frame 1 are mounted shafts 29 and a large sprocket30 and small sprocket 31. are mounted on each shaft 29, the largesprocket 30 being driven by a chain 32 from sprocket 24. The motion thustransmitted to sprocket 31 is carried to sprockets 11 by a chain 33,causing shafts 10 to be rotated, oscillating supporting arms 14downwardly and lowering the platform 21.

T he operation of my invention may briefly be described follows:

A radiator 50 that is to be tested for leaks is placed on the platform21, the radiator, of course, being connected to a suitable air supply(my invention having nothing to do with air or water connections) andthe operator releases the dog 28 whereupon he may rotate the shaft 22 bythe handles 25. The motion of shaft 22 is transmitted to sprockets 11through the chain 32, sprockets 30, 31, and chain 33, whereupon the arms14 are rocked downwardly lowering the hangers 17 and platform 21 intothe water. If desired the platform may be held in any position bylocking the sector 26 with the dog 28. Should it be desired to decreasethe distance that the platform descends into the tank 1, the nut 16 isunscrewed whereupon the arm 1 1 is given angular adjustment by rotatingdisk 15 the required amount, when the nut :is again tightened. Duringthe testing operation, if the operator desires to sup port the radiator50 in an upright position in order to inspect same, he may place sameedgewise on an opening 51 provided in the platform 21.

When it is desired to take up the slack in the chain the blocks 5 may bereleased from plates 6 by unscrewing studs 7, after which they areadjusted outwardly the amount required and the studs 7 again tightened.A slotted opening 34 in the tank wall permits the shaft 10 to be movedwith the block 5.

The advantage of providing the hangers 17 with hooks 19 lies in theirready detachability so that the platform can be removed from the tank inorder to clean the latter.

Obviously the invention is susceptible to modifications without.departing from the spirit of the same.

Having described my invention I claim:

1. In a machine of the character described, a suitable frame, a tanksupported thereby, a plurality of supporting arms rotatably mounted onsaid frame, l'iangers detachably suspended from the arms, a platformwithin the tank and secured to said hangers, and means for oscillatingthe supporting arms to raise and lower the platform.

2. In a machine of the character described, a suitable frame, a tanksupported thereby, a plurality of supporting arms rotatably mounted onsaid frame, hangers detachably suspended from the arms, a platformwithin the tank and secured to said hangers, means for oscillating thesupporting arms to raise and lower the platform, and means for angularlyadjusting the supporting arms to regulate the distance said platformmoves.

3. In a machine of the character described, a suitable frame, a tanksupported thereby, a plurality of supporting arms rotatably mounted onsaid frame, hangers detaehably suspended from the arms, a platformwithin the tank and secured to said hangers, means for oscillating thesupporting arms, to raise and lower the platform, and means for lockingthe platform in any predetermined position.

4. In a machine of the character described, a suitable frame, a tanksupported by said frame, a plurality of shafts mounted on the frame nearthe top thereof, said shafts having supporting arms on their inner ends,a platform detachably supported by said arms, an actuating shaft, a pairof counter shafts, means for driving the counter shafts from theactuating shaft, means for driving the first mentioned shafts from thecounter shafts,

whereby the platform may be raised and low ered, and locking means formaintaining the platform in any predetermined position.

in testimony whereof I hereunto atliX my signature.

ALBERT HORN.
